Men's 15km + 15km skiathlon
Under way. Four laps of the course in the classic style, then four laps in the free style.
If you can imagine, in the classic style sees the legs only separate slightly, with the arms working hard, while the free style is almost like skating on skis.
Already we've had a crash on the first corner, with Norwegian Simen Hegstad Kruger involved.
